What is the best way to store an array of integers in IndexedDB: TypedArray or ArrayBuffer?

Question

JavaScript

The task is to save lists of 32-bit unsigned integers (~1e7 values) in the user's browser.
They do not need to be searched, they are not indexed. Indexes are different - timestamp and all sorts of id.
I see three options:

1. data: [1,2,3]- regular array
   
2. data: new Uint32Array([1,2,3])- typed array
   
3. data: new Uint32Array([1,2,3]).buffer– ArrayBuffer.
   

Are there any fundamental differences with the so-called. occupied disk space and write / read speed? It will also be used on mobile devices.
I looked with FireFox devtools (Storage tab) - in the first two, the recorded values ​​\u200b\u200bare visible, and for ArrayBuffer it shows as a black box {}. And for TypedArray, it seems like it appends a key to each value. I use Dexie
to work with IndexedDB .
